Abstract

A light for an aircraft comprises a holder for carrying a first group of light emitting diodes arranged along a curvilinear line and a first reflector having an elliptic reflective partial surface defining a plurality of focal points forming a first curvilinear focal line coinciding with the light emitting sites of the first group of light emitting diodes and second focal point or curvilinear focal line. The light further includes a second optical unit comprising a single further focal point or curvilinear focal line that coincides with the second focal point or focal line of the first reflector. The light further includes a second group of light emitting diodes displaced axially with respect to the first light emitting diodes, which emit light that bypasses the second focal point or focal line of the first reflector of the first optical unit.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a light for an aircraft and, in particular, to an external light for an aircraft. While the present invention can be used primarily for each type of aircraft light, preferably the present invention is for a head light; taxi light, and runway turn-off light of an aircraft.

[0003] 2. Description of the Prior Art

[0004] In the past, in the technical field of aerospace applications, light sources have been based on gas discharge technology or filaments. For several years, aircraft lights based on LED technology have found ever stronger commercial use. Examples for LED-based aircraft lights for different purposes are disclosed in U.S. Pat. No. 6,679,618, U.S. Pat. No. 7,572,030, US-A-2007 / 0164875, WO-A-2009 / 156349, EP-B-1 217 663, EP-B-1 264 767, EP-B-1 552 983, EP-B-1 836 437, and GB-B-2,350,176.

[0005] In order to fulfill the official requirements of the Federal Aviation Association (FAA) with re...
